Emgu CV does not detect CUDA

Question

I have GeForce GTX 960 with installed 353.90 NVidia driver and 7.5.18 CUDA driver. I'm using the latest version of Emgu CV, but it doesn't detect CUDA on the system (even in Emgu samples), Emgu.CV.Cuda.CudaInvoke.HasCuda is always false. At the same time other programs, like Xillisoft Video Converter can use CUDA without problems. How do I enable CUDA for Emgu CV?

Answer 1

Make sure you're building an x64 app. If your build configuration is set to AnyCpu, uncheck the "Prefer 32 bit" box under Project properties -> Build. OpenCV has dropped support for x86 CUDA following NVIDIA CUDA v7.
